Product Details
LPR N Valve Standard Downhole Tester Valve For Drill Stem Testing
Valve
The LPR N Tester Valve is a standard tester valve in drill stem
testing service. The N valve is a full-opening, annulus
pressure-operated valve. The full bore design of tester valve
permits measuring multiple closed-in pressures in cased holes where
pipe manipulation is restricted and a full-opening string is
required.
The nitrogen chamber of LPR N Valve is charged at the surface to a
selected pressure determined by surface temperature and bottomhole
temperature and pressure. If the intended test requires a permanent
packer that uses a stinger mandrel or seal nipple, a variety of
Halliburton bypass tools are available, depending on field
application, to help ensure that the formations and downhole
equipment are protected from excessive pressure build up.
